' ROBERT L- JO HNSO'N, 0F ATMORE, ALABAMAc' Application fil-ed Septembcr-20, 1e21, s ria no.- 5oI,e28.

To all whom it may concern; I

Be it known that I, ROBERT L, J ornvsow,

a citizen of the United States,,a-nd a resident of Atmore, in. the county of. Escambia and State of ;Alabama,have invented certain new and useful Improvements in- Plo-ws, of which the following :is a specification.

My invention relates to;improvementsin plows, and has for. its object to ;provide an improved plow which is adapted. to. perform the various earth working operations without requiring several different types of plows, and whichv is 'ofsimple and durable construction, reliable in operation and easy and inexpensive to manufacture.

Other objects and advantages of the invent-ion reside in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying dlrawings forming part of this specification, and in which:

Figure 1 is a perspective View illustrating the invention adapted to perform the function of the turn or mold board plow;

Figure 2 is a detail perspective View of a mold board;

Figure 3 is a similar .view of the point;

Figure 4 is a similarview of the runner;

Figure 5 is a similar view of the brace;

Figures 6, 7, 8 and 9 are perspective views of diverse forms of shove-l plows adapted to be selectively employed; in conjunction with the present invention; and

Figure 10 is a view. illustrating the harrow adapted to be employed with the present invention.

Figure 11 is a fragmentary view, partly in elevation and partly in vertical section, showing the construction of the plow standard.

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention, the numeral 10 designates the plow beam. having a clevis 11 at its forward end and having handles 12 connected thereto. 13 depends from the beam and is braced bv means of a brace 14. The standard 13 is provided with transverse bolt holes 15 and longitudinal bolt holes 16, the transverse bolt holes being arranged adjacent the lower end of the standard; and the longitudinal bolt holes being arranged above the transverse bolt holes.

A standard v The mold boardor turning plowemployed in this invention is'ofa specialconstruction, and asshown in Figuresl to fl inclusive com prises a runner 17 taking .the form of'a three sided polygon and converging toward its forward end. One side of the-runner is curved! and .is formed to constitute a. ci'itting edge, as indicated at, 18. Themold board is arranged on the runner and'consists of a. curved plate 19' having an inturnedflange 20 along its lower side which rests upon the runner. The mold board and its firing-e20 are curved correspondingly to the curved cutting edge 18 of'the runner, and the mold board is spaced slightly from this edge. The runner and theflange 20 are provided with registering bolt holes, indicated at 17 and 20?, respectively, through which bolts or other fastenings are extended to secure, the P mold board in the runner. A brace 21 is. also provided and has one end secured to the curved plate 19 constituting the mold board and has its other end secured to the runner. At its forward edge the mold board is provided with an offset flange 22 constituting a seat. A point 23 has a portion received on the seat and secured thereto by rivets 24, the point 23 having a cutting edge 25 and having a flange 26 provided with a. cutting edge 27 and engaging under the forward edge of the runner. The flange 26 is complementary in its action to the action of the runner serving in this respect as an auxiliary runner for the projecting portion of the point 25. Connecting means are providied for securing the turning plow tothe standard 13 and preferably consists of a connecting bar 28'having bolts 29 connecting it to the mold board and bolts 30 extending through the cross bar and through the transverse bolt holes 15 provided in the standard.

When it is desired to use a sweep shovel or heel scrape-r the mold board or turning plow is detached and one of the earth working elements shown in Figures 6, 7 8 or 9 is employed. It is to be noted that all of these elementsinclude a connecting portion, designated at 31, 32, 33 and 34, the connected portions having bolt holes 35, 36, 37 and 38, respectively, the bolt holes being adapted to receive a bolt which also passes through the longitudinal bolt hole 16 of the standard 13. A harrow designated at 40, may also be employed in lieu of the other earth workingelements, the harrow having for this purpose a connected bar 41 provided with a bolt hole 42 adapted to receive the bolt extending through the longitudinal bolt holes 16 of the standard 13 whereby the harrow is connected to the standard.

In this manner any desired type of earth working element may be utilized with the same plow stock by simply attaching it to" dinal bolt holes, a runner comprising a flat plate converging toward its forward end .and having a curved knife edge, a mold board consisting of a curved plate having a flange restlng on the runner and secured thereto and an oflset flange at its forward end constituting a seat, the mold boardhavmg a curvature corresponding to the curved edge of the runner, a point having a portion received on said seat and secured thereto, a,

brace connecting said runner and said mold board, a connecting bar secured at one end to said mold board and having bolt holes at its other end vregistering with the bolt holes of the standard, and bolts extending through said registering bolt holes. 2. In a plow, arunner comprising a flat plate converging toward its forward end and having a curved knife edge, a mold board consisting of acurved plate having a flange resting on the runner and secured thereto and an offset flange at its forward end constituting a seat, and a pointhaving a portion received on said seat and secured thereto and having a cutting edge and'a flange com plementary to the runner.
